    if you are doing the getAt right after load, the store isn't loaded at that point. Loading is asynchronous so you have to do this code after the store has loaded

    Code:
    store.on('load', function(store) {
        var rec = store.getAt(0);
        combo.setValue(rec.get(combo.valueField));
    }, store, { single : true });

    Sorry , may be it becomes ??? , but I got confused :
    I put that code into listeners ( as u can c in code above ) I defined store and created it and panel
    with combo in application. Combo has listeners where I put that code ( or should I put it somewhere else)
    beforerender:function(combo,opts){
    store.on('load', function(store) {
    var rec = store.getAt(0);
    combo.setValue(rec.get(combo.valueField));
    }, store, { single : true });


    }
    }
    .. but still getting nothing

    Ok... you need to stop just copy and pasting code. You need to look at what the code snippets are doing and understand it. In your beforerender listener, is the variable 'store' defined when you do store.on? Or do you need to get the store from the combo parameter in that function?
